This combined type Pressure Reducing cum Desuperheating control valve is a compact yet effective and carefully designed device. The DeFlo SCV eliminates all common issues faced by combined type steam conditioning valves.

The SCV is the most efficient way of steam conditioning where the water is injected in a highly turbulent area to ensure most efficient water to steam mixing. The DeFlo SCV are available in Standard, Angle and Expanded outlet configuration.

No special expertise is required to operate or maintain the DeFlo SCV as it utilizes most spares of a Standard GFlo Globe Control valve with an addition of a Thermal Desuperheating Sleeve at its outlet. This spray method protects the valve belly from pitting and thermal shocks/stresses unlike most competitive designs. This also reduces the SCV maintenance costs as the Valve and Trim life is greatly enhanced.

With an extended knowledge of Control Valves and Desuperheating units is one of the only two specialists in the world who are in the field of Pressure Reducing and Desuperheating.

Superior performance in liquids and gaseous services is the hallmark of the Globe Control Valve. Easy, quick and economical maintenance makes the Globe Control Valve more user-friendly. The spring cylinder actuated imparts stiffness and maintains very high precision in positioning, strong response, repeatability and controlled high-speed movement are the characteristics absent in diaphragm operated control valves. Globe Control Valves has the thrust capability to shutoff against higher fluid pressures as it can handle up to 150 Psi / 10.30 Bar air supply.

Valve closure is totally dependent on springs in most diaphragm actuators. The unique design of these valves enables it to combine the spring force, fluid pressure and supply air pressure to achieve an extremely tight shutoff. A self-aligning seat ring adds to and further improves the shutoff capability.

Galling at cage is the culprit in many common maintenance issues with globe valves because of the close metal-to-metal contact between plug & cage. It has two top heavy duty stem guides. Contact between the plug and seat retainer is completely avoided. Easy and quick maintenance is permitted due to clamped-in seat and top entry trim.

The differential bypass valve is used in systems where heating loads may be excluded from the circuit as zone valves close. It controls the excess flow in the system by acting as a bypass while ensuring adequate flow to the remaining open circuits. The differential bypass valve helps reduce velocity noise caused by excess flow through the circuits while maintaining the pump head at a constant value.

Installation:
The differential by-pass valve should be installed after the pump between the supply and return piping. It can be installed either in the horizontal or vertical position provided it is in accordance with the direction of flow as indicated by the arrow on the valve body.

The Flo offers a high-performance rotary globe valve which provides precision control over extended life span through enhanced safety. The Flo is a high performance, safety focused, economical, yet feature-rich, Eccentric Rotary Plug control valve for applications demanding higher rangeability, precise control, and higher flow capacity.

The Flo valve offers rangeability up to 160:1 - compared to 50:1 for typical globe control valves and 20:1 for most butterfly valves.

A heavy-duty, non-crossover shaft is out of the valve’s flow path. This superior design allows higher flow capacity for a given valve size. It also eliminates shaft damage from erosive process fluids. Many competitor designs use a straight-thru shaft which presents an obstruction to the flow, limiting capacity and presenting a target for erosion.

The Flo offers positive, anti-blowout protection by means of a separate bonnet and integral shaft collar, as a standard option, emphasizing its status as the safest Eccentric Rotary Plug valve on the market. The end-post shaft is designed so there is no possibility for it to be lost downstream. The end-post is rugged, precision machined, perfectly aligned, and positively retained so movement is smooth and precise. The oversized shaft provides improved reliability and valve life by eliminating shaft failures and reducing bearing wear.

Non-Crossover Shaft

• Pocket-less flow-path tolerates slurries, even up to 3% paper stock.
• Unobstructed flow when fully open.
• Up to 70% greater capacity than other ERP control valves.
• Not eroded by process-born particles.

Eccentric Rotary Plug

• The plug does not rub seat ring. Less wear, less friction, more precision.
• Stable throttling, low dynamic torque
• Stable throttling in either flow direction
• Inherently Linear characteristic
• Flow direction assists movement to safety position on air-failure
• Robust, rigid seat and plug give increased durability
• Tight Shut-off, Class IV (Metal Seat), Class VI (Soft Seat), even after prolonged usage
• Separate Bonnet and Integral Shaft Collar: A positive anti-blowout as a standard feature, in full compliance with ASME B16.34 Section 6.5.1, ensures that the shaft cannot blow out, even if the actuator is removed.

Trim Choices & Plug Design:

• Hardened plug gives high performance and long service life.
• Flow Capacity can be closely matched to the process application.
• Full Area, 75 / 70%, 40% seats are economical to replace when optimizing flow capacity or changing service conditions.
